Dual Pro Charge-On-The-Run with 2 12V Outputs CRS2

The Charge -on-the-Run product has been great for anyone who needs to charge up to two extra batteries from their alternator while running down the lake. The unit basically acts as a set of jumper cables, once the main cranking battery has reached it's full alternator charge. The unit will then stay on while running the engine and switch back and forth between two additional batteries and put as much charge into the auxiliary batteries as time will allow. It's great for bass boats, pontoons and runabouts.
